Do you need to turn on oxygen every day for raising tropical fish? 5

Oxygen is enough, not too much.

What are the disadvantages of being in a state of hypoxia in fish for a long time:

1. When the fish are in a state of hypoxia for a long time, it will lead to low appetite, which is actually very easy to understand, just like us humans, if we are hypoxic for a long time, we naturally have no appetite.

2. When the fish are in a state of long-term hypoxia, the growth rate of the fish will be delayed, and they may even suffer from various diseases.

When the oxygen in the water is less than 3 milligrams per liter of water, the fish will grow slowly and will be less resistant to disease. When the dissolved oxygen per liter of water is higher than 5 milligrams, the fish will grow normally, and the fish will swim around, and the fish will grow 20% 30% faster than the fish growing at 4 milligrams per liter of dissolved oxygen per liter of water! In addition, the fish will be very active, with strong foraging behaviors and characteristics.

The importance of oxygen in the water to the fish is self-evident, and in addition to the fish, many aerobic beneficial bacteria in your fish tank also need oxygen, as well as the decomposition process of organic matter in the water, as well as the conversion process of ammonia nitrogen nitrite, all need the help of oxygen. These are all necessary elements that the fish need.

If the fish tank is larger, you don't need to be oxygenated all the time, because the oxygen in the large fish tank will not be consumed in a short time. If the fish tank is always filled with live water and the fish tank has a good filtration system, there is no need for proofing at all, because the live water will continue to carry oxygen into the fish tank.

If the fish tank is relatively large, you don't need to keep oxygen, because there is more water in the large fish tank, and the oxygen content in the water will be more, even if the oxygen is stopped, the oxygen in the water will not be consumed in a short time.

In addition, if there is always live water injected into the fish tank and it is well filtered, there is no need for oxygen at all, because the injected live water will carry oxygen into the fish tank, and the water in the fish tank will not be hypoxic.

It should be noted that in case of high temperature and rainy days, the air pressure is low, and the oxygen content in the water is also very low.

Raising tropical fish does not need to be oxygenated all the time, and the fish tank has a great relationship, the fish tank is small and needs oxygen, and the reasonable tank body is generally filtered, and there is no need for oxygen.

And any living thing needs oxygen to survive, without oxygen there is no life, and the survival of tropical fish is also inseparable from oxygen. The oxygen needed for the survival of the fish is obtained by absorbing the dissolved oxygen in the water through the microvessels of the gills, and then brought to and by the blood circulation system, and the carbon dioxide excreted is also carried out through the microvessels of the gills.

1. If oxygen is not required: reasonable water environment. The amount of dissolved oxygen in the water directly affects the growth of the fish, so it is necessary to ensure that there is enough dissolved oxygen in the water.

In addition to being obtained by mixing with water and changing water, dissolved oxygen in water can also be produced by photosynthesis of aquatic plants in water. That is to say, if there is a large enough tank and fruit, there is no need for oxygen.

2. Situations that require oxygen: lack of light. Without light aquatic plants, they cannot photosynthesize, absorb carbon dioxide and produce oxygen, and plants cannot sustain themselves.

However, plants also have certain requirements for light, and if the light is too strong or the light time is too long, aquatic plants will grow green moss, which will affect the photosynthesis of aquatic plants.

If you are raising small tropical fish, as long as there is a filtration cycle, you can basically do without an oxygen pump.

Because the filtration cycle itself has the effect of circulating oxygen in the fish tank.

Depending on the size of your fish tank, if you have a submersible pump to circulate the water tank, it is not necessary. No, if the fish tank is small and there are many fish, then it is useless to use the air pump!Because the water cannot be recycled, the fecal food residue will ferment to produce nitrogen, and because the water cannot be recycled, the water temperature cannot be lowered, and generally speaking, if the temperature is high, it will become fish soup.

Therefore, if you want to raise fish well in the summer, you must have a square fish tank of suitable size (the kind of round one cannot be equipped with a submersible pump device), a submersible pump system, and a thermometer (to measure whether the water temperature is over 30).

The nitrifying bacteria in the fish tank need to be oxygenated all the time. The nitrifying bacteria in the fish tank need oxygen to maintain the balance of water quality and maintain clear water quality. If the oxygen supply is stopped, the water will slowly become turbid until all the nitrifying bacteria die.

Stop the filtration and oxygen, and the bacteria will slowly die after 2 hours. Generally, after 48 hours, the bacteria in the tank will die in large pieces, and it is difficult to return to a normal state. When we raise fish, we fill the tank with oxygen.

The water in the tank produces a type of bacteria, and over time, the bacteria multiply, and the water becomes very clear. It is worth noting that do not try to save electricity to stop the oxygen supply to the fish tank, the fish will die in a low oxygen environment.

1. The growth of nitrifying bacteria in the fish tank requires a large amount of oxygen, and after the oxygen supply is stopped, the water quality will gradually become turbid

In the small ecosystem of the fish tank, oxygen is always needed. Fish don't need much oxygen, which is mainly supplied to nitrifying bacteria. The more oxygen this bacterium needs to grow, the better it will grow.

If you don't get enough oxygen, the bacteria in the tank will deteriorate and you won't be able to maintain the balance of water quality.

2. The nitrifying bacteria die after 2 hours, and after 48 hours, they will die completely

When we use the fish tank to raise fish, we must not stop the oxygen supply to the fish tank in order to save electricity, because the oxygen in the fish tank needs to be supplied 24 hours a day. If we don't get oxygen for 2 hours, we will find that the crystal clear water has turned white, which means that the nitrifying bacteria are dying. At this point, we immediately oxygenated the fish tank, and the water was back to its original state in a very short time.

If the oxygen supply is stopped for more than 48 hours, the water will become muddy. At this point, no matter how much oxygen is supplied, the water quality will be difficult to recover.

So, do you know why fish tanks supply oxygen?

The fish tank does not need to be oxygenated all the time.

If the density of the fish tank is large, it must be oxygenated all the time, if the density is small, it does not need to be oxygenated 24 hours a day, and it can be fixed and oxygenated several times a day.

The effect of oxygenation can increase the density of oxygen in the water, so that the oxygen in the water is evenly matched, which is conducive to the survival of fish and aquatic plants in the fish tank. It can produce a stable flow in the water, which is conducive to the growth of fish.

If oxygen is not required:

It is best not to raise goldfish with additional oxygen, especially the high-power aeration pump, not to mention the kind that will also make flow. Although goldfish are high oxygen consumption aquarium fish.

However, they are also not suitable for too much water flow, if the aeration pump will stir up too much water, the goldfish need to maintain balance in the water, the body will inevitably tilt, and over time the body's swimming posture may change, if it is serious, it may also lead to loss of sight.

The fish tank is too small and don't oxygen, some fish tanks are only 20 cm in length, and the water body is small, plus the water flow stirred up by the aeration pump, the water in the whole fish tank is basically in turmoil, and the fish in it can't stand it, after all, they also need to rest.

In particular, some small tropical fish, the most common guppies, if the current is constantly turbulent and very large, then it is likely that the fish will die of exhaustion.

These two situations are more common when you don't oxygenate the fish tank, in fact, there are still many aquarists who have experienced them, and I hope you can correct them in time if you have these two situations.
